Since the last upgrade of org-plus-contrib to 20170210 I can no longer create clock tables in org mode. Computing the begin statement creates an empty table (see below) and throws the error
org-clocktable-write-default: Wrong type argument: char-or-string-p, nil.
#+BEGIN: clocktable :maxlevel 5 :scope tree2 :tcolumns 1 #+CAPTION: [2017-02-12 So 14:42] | #+END:
I have not changed anything in the clocked tree nor in the init file. So, to me it seems that the error results from changes in the org-clocktable command. Have you also run into this error? Has anybody found a solution to that?
UPDATE from 27.02.2017: The clocktable command works if I duplicate a single org file and run it as a different user with a not customised init file. Does anybody has a tip how to interpret the error message, so I can find the causing error in the init file?
